The Relationship Between Corporate Governance Quality and Accounting Information Affecting Investment Decisions in Securities of Listed Companies in The Stock Exchange of Thailand SET 100
Main Article Content
Abstract
This article aimed to study (1) examine the relationship between corporate governance quality and company securities that influence the performance of listed companies on the Stock Exchange of Thailand, and (2) investigate the relationship between accounting information and company securities of listed companies on the Stock Exchange of Thailand. This research is a quantitative study utilizing secondary data collected from financial statements (annual financial data from 2019 to 2023) of 490 companies listed in the SET100 index. The researcher applies the Ohlson model as the statistical framework for data analysis, employing methods such as descriptive statistics, correlation coefficient analysis, and multiple regression analysis. The research results were found as follows: (1) Corporate governance quality is associated with company securities, which in turn affect the financial performance of listed companies on the Stock Exchange of Thailand. Key factors influencing investment decisions include the book value per share (BVPS), earnings per share (EPS), the number of risk management board members (Ac Risk), the company's capital structure (EA), financial performance (ROA), and investment level (FFA), which collectively explain 35.90% of stock price variations. (2) The relationship between accounting information and accounting profit collectively explains 25.70% of stock price variations. When comparing the explanatory power of these factors, corporate governance quality provides greater benefits for investment decision-making than accounting information.
